You can find detailed instructions on how to install ArgoCD here
For your convenience, you can find commmands to install Argo below :
VERSION=$(curl --silent "https://api.github.com/repos/argoproj/argo-cd/releases/latest" | grep '"tag_name"' | sed -E 's/.*"([^"]+)".*/\1/')
sudo curl -sSL -o /usr/local/bin/argocd https://github.com/argoproj/argo-cd/releases/download/$VERSION/argocd-linux-amd64
sudo chmod +x /usr/local/bin/argocd
kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
Please follow the rest of the documentation to
- expose your the ArgoCD UI
- get access by retrieving the password
TL;DR
# Get initial admin password
kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d && echo
# Login with the CLI
argocd login --insecure --grpc-web --port-forward --port-forward-namespace argocd
# Username: admin
# Password: <the one you just retrieved>
# Update password
argocd account update-password --insecure --grpc-web --port-forward --port-forward-namespace argocd
# Access to the UI (open a new terminal to enter this command to avoid being distrubed by outputs)
kubectl -n argocd port-forward --address 0.0.0.0 svc/argocd-server 8082:80
# Open UI at http://<uid>.int.be.continental.cloud:8082
# Login with the new credentialsThis example modifies files within the repository, so you will need to configure your local environment to push to your github repository or to make your commits directly in github web UI.
If everything went fine so far you should now see the ArgoCD UI.
Now either click on New App at the top or Create Application in the
middle of the screen. This will open a screen like this. We will walk through
the configuration in the next part.
Now we have to define the proper parameters for your application.
For the application we define podtatohead as the application name and leave
the project to default. We also check autogenerate namespace to
have ArgoCD take care of namespace management.
Use the Github repo you forked before and ensure you set the path to delivery/chart. This will use the Helm of the tutorial
In the example we use the local cluster as our destination and
podtato-argocd as the namespace to deploy to. As we checked autocreate namespace above ArgoCD will create the namespace for us.
ArgoCD will automatically detect the Helm values files. We do not need to change anything here and just can leave it as it.
Now hit create application and it should be visible in the project overview.
If you cannot see the application ensure that the filters are set properly.
The application will show up yellow as it has not been synced yet.
In order to sync and deploy the application, click sync at the bottom of the application square.
A new panel appears to show every resource that will be synchronized : click synchronize to validate.
This will now create all application ressources in the cluster. Once syncing is finished you will see all application components as healthy.
And if you go back the the Applications view, your application is now synched and healthy
Updating the project required to update the values file in the
/delivery/chart folder fo your Git
repository. Change some tag values to another version (v2-latest-dev,v3-latest-dev,v4-latest-dev).
Push your modifications to git (either in your terminal or by using the github web UI)
The application will now show up as out of sync. Simply hit sync and
the application should update
Access the podtato demo application again and you should see the new version.
